Measurements were made of the crew compartment vibration environment experienced in the B-58 aircraft during low-altitude, high-speed flight. Data were obtained of the longitudinal, lateral and vertical linear accelerations and the roll axis angular velocites and accelerations present during five flight made in July 1966. The terrain contour following flights at 500 to 900 feet above the flat to semi-mountainous regions of Louisiana and Arkansas were conducted at 450 knots true airspeed. Data analyses included probability density and distribution and the auto-power spectral density functions in addition to tests for stationarity, randomness and normality. The individual degree-of-freedom results are presented in graphical and tabular form and allow evaluation of operational flight environments and exposure conditions in terms of existing tentative vibration exposure criteria for various crew functions. They will also form the urgently required basis for simulating these environments for further biomedical laboratory research on human tolerance and performance. Author
